then perhaps Rebel-users would be prepared to part with 2 grand for a body like this?
Don't think so... "Rebel-Users" mostly upgrade to something 'bout $900-1500 and I can't see them spending $1999 + Lenses (since most own EF-S-lenses anyway).
Yup, that sounds about right. I'm a rebel user that upgraded to a 7D. I don't have a problem with the T2i IQ, but it was a pain to catch action shots. I usually have to pre-focus at a certain distance and wait for the subject to get there. As for IQ, I have a few 20" x 30" prints and they look just fine to me.
Just my opinion here, but I think most rebel users, like me, already think the IQ is excellent. If I didn't have to shoot sports/action, I'd be perfectly happy with my $650 T2i. Great stills, plus excellent video to boot.
